Manufacturing process of HDPE micro foamed extrusion molding board

Abstract

A manufacturing process of an HDPE micro foamed extrusion molding board comprises the following steps of (1) mixing, (2) drying, (3) screw high-temperature stirring and extruding, (4) mold forming, (5) cooling and sizing and (6) cutting. The manufacturing process has the beneficial effects that according to the manufacturing process, an HDPE mixture is foamed and expanded in a screw through micropores, and a solid board with grain similar to cellulite grain or annual ring grain or tiger skin grain on the surface is manufactured through mold sizing; and for furniture products manufactured through the plate, product strength is effectively improved, the texture enjoyment of the products to enjoyment and tactile sensation is improved by means of regular granular convex-concave grain on the surfaces, and after being launched on the market, the products are deeply sought after by foreign clients especially Europe and America clients. The traditional manner of manufacturing furniture throughsolid wood is replaced, wood cannot be rotten, the wood is not prone to being faded after being colored, due to the fact that HDPE granules belong to elastic bodies, cracking and breaking off are notprone to happening, users feel comfortable when lying on and sitting on the products, the added value of the products is greatly improved, and the service life of the products is greatly prolonged.

Description

Technical field: [0001] The invention relates to the field of manufacturing micro-foamed boards, in particular to a manufacturing process of HDPE micro-foamed extruded boards. Background technique: [0002] The current solid wood furniture, especially outdoor solid wood furniture products, due to the natural properties of wood, after long-term exposure to the sun and rain in the air, it is very easy to naturally crack, rot, fade, etc.; Low comfort; at the same time, wooden furniture needs to go through raw material drying, planing, sanding, repairing and polishing, paint coloring and other processes in the production and processing process, which requires a lot of manpower and energy consumption, especially the waste gas and waste water in the drying and painting process The emissions will also damage the environment, the added value of the product is low, and it is difficult to transform and upgrade; the current extruded boards such as PS, WPC and other imitation wood furni...

Problems solved by technology

[0002] The current solid wood furniture, especially outdoor solid wood furniture products, due to the natural properties of wood, after long-term exposure to the sun and rain in the air, it is very easy to naturally crack, rot, fade, etc.; Low comfort; at the same time, wooden furniture needs to go through raw material drying, planing, sanding, repairing and polishing, paint coloring and other processes in the production and processing process, which requires a lot of manpower and energy consumption, especially the waste gas and waste water in the drying and painting process The emissions will also damage the environment, the added value of the product is low, and it is difficult to transform and upgrade; the current extruded boards such as PS, WPC and other imitation wood furniture products have a smooth surface and no texture, are heavy and brittle and have a short service life. Compared with traditional solid wood products, there is no obvious differentiation advantage, and the plastic feeling is too strong
